Solar phone chargers fall into two categories: panel-only chargers that feed power directly to your phone in real time, and solar power banks that store energy in a built-in battery for charging later. Panel-only models are lighter and charge faster in direct sun, but they stop delivering power the moment you step into shade.
Solar power banks let you charge the battery during the day and plug in your phone at night, though their small built-in panels are usually 1W to 3W and take days to fully recharge the internal battery from solar alone.
Advertised wattage rarely matches real-world charge speed. A panel rated at 20W under ideal lab conditions typically delivers 12W to 15W in actual sunlight due to angle, temperature, and cloud cover.
That means a phone that charges in 90 minutes from a wall outlet will take three to four hours from a 20W solar panel on a clear day. USB-C output with Power Delivery support charges modern phones significantly faster than USB-A, which caps at around 10W to 12W.
Below are 10 solar phone chargers compared by panel wattage, real charging speed, output ports, and portability for hiking, camping, and travel.

What Separates a Good Solar Charger from a Great One
Battery capacity in this roundup runs from 10,000mAh up to a massive 36,000mAh, and every pick includes either a built-in battery or a foldable panel for direct charging. The BLAVOR tops the list by combining 20W USB-C fast charge, wireless output, and IPX5 waterproofing in a single unit.
If you are choosing between a power bank and a foldable panel, know that panels like the BigBlue 28W charge faster in direct sun but store nothing for later. Power banks give you juice after dark at the cost of extra weight in your pack.

This product is best suited for someone who does not need to rely heavily on the solar charging feature.
Final Thoughts
The split between solar power banks and foldable panel chargers is the first decision to get right. Power banks like the BLAVOR 10,000mAh store energy for later use, so you can charge your phone at night in your tent.
Foldable panels like the BigBlue 28W generate more wattage in real time but leave you with nothing once the sun goes down.
Battery capacity numbers can be misleading if you ignore charging speed. The ANYFONG’s 36,000mAh sounds massive, but its small solar panel tops it off slowly.
The BigBlue panel pushes 25.4% efficiency and fills a phone noticeably faster in direct sunlight, even without a built-in battery.
Wireless charging is convenient but drains the power bank faster than wired connections. We saw roughly 30% more battery use on the BLAVOR when using Qi versus the USB-C port, so keep that in mind if you are trying to stretch your charge over a multi-day trip.
If you want something even lighter for ultralight backpacking, our roundup of the best ultralight solar chargers covers panels that weigh under a pound and still deliver solid output on the trail.
